DBTKDT Posted January 19, 2011 Report Share Posted January 19, 2011 Hey guys, just wondering? I have a set of LS1 heads(241) off my 04 GTO that only have about 6000 miles on them. Is there any positive benefit putting these heads on a LQ4? or what if i head work done to them? Just thinking, i have a set of heads here so maybe i can get them worked and not have any down time? Looking for your thoughts? Thanks! Quote Link to comment Share on other sites More sharing options...
sierra ss Posted January 20, 2011 Report Share Posted January 20, 2011 241 specs. 317 specs. CCV= 66.67cc 71.06 INTPV=200cc 210 EXHPV=70cc 75 INTVD=2.003 2.00 EXHVD=1.55 1.55 You will see a bump in CR but a slight loss in flow. I would have them ported. Im currently working on a set of 4.8 heads to go on my LQ4. Same flow as LS1 heads but with a smaller INTV and 61 CCV. Even not porting IMO they would do good. Go for it and tell us how it worked.

zippy Posted January 20, 2011 Report Share Posted January 20, 2011 Due to the poor flow of the 241's, I wouldn't recomend them. You might gain some torque with the compression gain, but no real hp gain due to the flow difference. If you're going to have a set ported, you're better off with some 862's or 243's.
